What are the methods to avoid noise in powder metallurgy gears?
Author:
To avoid noise from powder metallurgy gears, the following methods can be considered:
1. Optimization design: Ensure that the gear design is reasonable, including the selection of parameters such as tooth shape, modulus, and tooth thickness, to reduce the impact force and noise during meshing.
2. Raw material selection: High quality powder metallurgy raw materials are selected, which have good wear resistance and lubrication, helping to reduce noise.
3. Manufacturing process control: In the manufacturing process of powder metallurgy gears, strictly control process parameters such as sintering temperature, time, etc. to ensure the quality and accuracy of the gears.
4. Lubrication treatment: Use appropriate lubricants to lubricate the gears, reduce friction and wear, and reduce noise.
5. Gear accuracy: Improve the machining accuracy of gears, ensure good meshing of gears, and reduce the generation of noise.
6. Installation and calibration: Install the gears correctly, ensure the coaxiality and verticality of the gears, and avoid noise caused by eccentric loads and vibrations.
7. Shock absorption measures: Use shock-absorbing materials or structures to reduce the vibration transmission of the gear transmission system and reduce noise.
8. Maintenance: Regularly inspect and maintain gears, clean tooth surfaces, and replace worn parts in a timely manner.
9. Noise testing: Conduct noise testing during the production process, promptly identify problems and make improvements.
